Here is my '77. I bought it new in March '78. Have enjoyed it for almost 37 years!
Jardine 2 into 1 muffler, Gary Bang large-finned aluminum header clamps, Koni shocks, drilled brake disc, VM-34 Mikunis, K&N filters,
Side covers modified to fit around filters, Halogen Light, superbike handlebars (with "Bar-Snake), in this photo (recently changed back to stock bars) Tapered roller bearings in steering head. Home-made crankcase breather.
All unnecessary cast letters like "Kickstarter", and numbers like the shift pattern around the shift-shaft have been ground off and the cases polished.
